It's hard to say really, I like the characters in Marvel more, but recently DC has been pulling some really awesome stories in many of the Batman books(that goes for the bat family really, Nightwing, Batman and Robin, Batwomen, etc.), Animal Man, and The Swamp Thing. Even Aquaman has been awesome to read It's also easy to forget Watchmen and Sandman(two of the greatest graphic novels) came out from DC. Marvel has had awesome crossovers and events, something DC didn't have much of. It's hard to say, but I've always been a marvel person all around, due to Spider-Man being my favorite hero. Overall though they have their ups and downs.
